If and when he does leave do you have any recommendations as to what I could put in the agreement to where he shall need to pay to have the house cleaned or carpets replaced, etc, etc if there are clear signs of use from a dog? 

From here I will speak with a lawyer to see how I can most cleanly severe ties with this contractor.

I checked with a few of them, and none had any major headaches and said the tenants were generally very clean and collecting rent was never a problem, since the IC wants to keep property owners happy so they continue to rent places to their refugees.I've checked the unit myself a couple of times, and it's true, it's nearly as clean and tidy as the day I put it up for rent.

Based on pictures, the current owner and the tenets appear to have keep the property clean.

I could probably just do a clean up and put it right back on the market after I buy it. 

Meaning I have he connections to help get the property cleaned, repaired, and rent ready.

Hi-We're making an offer to buy SFR.How can we add terms to require the property is title clean, free of any lien (tax lien etc)?

If you can offer nice, clean, fresh and modern you will always be fully rented.On another note: I totally get it.

I have now jumped to a more abstract approach contacting extermination companies carpet cleaning companies  and other sources that come in direct contact with landlords And have offered them incentives for leads for those who know landlords ready to sell.

Before replacing it I had it cleaned professionally but odor remained.
